ANTOINE DESBAINS, F -MONTREAL, QUEBEC, CANADA MEASURING DEVICE.

Applicationfiled July 1;

' T 0 all whom it may concern:

Be it known that I, Axroixn DnsBAINs, a subject of the King-"of Great Britain, residmg at Montreal, in the Province of Quebec and Dominion of Canada, have inventednew and useful Improvements in Measuring Devices, of which the following is a 'speci:

f fication.

I My pre sent'invention pertains to measuring devices; and it'has for its object to provide a device" that is highly. ad'vantalated to indicate: immediately thecorre'ct angle and thereby save Considerable time.

The invention .in all of 'its details will be fully understood from the following description and claims when the same are read in" connection with the accompanying drawings, hereby made a part hereof, in which:

F gure 1 is a new-illustrative of the use of my novel device in connection with a tapered shaft. I

-Figure.2 'is a side elevationof thedevice per se.

Figure 3 is an elevation of" the opposite side of the device] F iguresa and 5 are elevations showing the opposite ends of the device.

Figure 6 is atransverse section-showing the mounting of the endwise movable transverse bolt.

Figure 7 is a View showing the application of the deviee for measuring the angle of a bore. a

Figure 8 is a transverse section of the device, which section is hereinafter explicitly referred to. This section is at right an gles to that of Figure 6.

Figures 9, 10 and 11 are views of a modi I fication.

Similar numerals designate corresponding parts in Figures 1 to 8 to which reference will first be had. I

As will be readily noted, by partihular reference to Figures 2 to 6. my novel device includes. among other elements, a body plate 1. The said plate 1 is provided with opposite wings 2. in which are aligned slots 1, the inner portionsof said slots extending into the inajor portion of the plate, as illustrated. Adjacent to one end the major por- 'tion of the body plate 1 is provided with a transverse threaded aperture 5, Fig. 3,- tore- Specification of Letters Patent. 1

.' and has its inner v Patented Apr; 4, 1922. 1919. Serial No. 307,907.

ceive the threaded shank of a headed screw 6 At its opposite end the said major poltion of the plate 1 is provided With a gtaduated scale 7, and located adjacent to. the last-named scale-T is an endwise movable bolt 8, that is disposed through the body plate. Said bolt '8 is headed at 9 and reduced and threaded at its opposite end as indicated by'10, Fig. 6, and is provided with alongitudinal groove 11. Its'shankextends through the plate and through a sleeve '12 at the back of the plate, and it is designed to be adjustably fixed in-position by aset screw 13 that bears in the said sleeve 12 v end adapted to enter. the groove 11. A nut 1 1 is removably arranged on the threaded end 10 of the bolt shank, and henceit will, be manifest when said nut 14: is removed and the SCIGW'I?) is. turned out having pointers 18 at right 'angle's to their ma or portions and adapted to' cooperate with the scales 3. In the said pointers" are apertures 19, and extending through the slots 4: in the wings2 and through the slots v16 in the plates 15, as well' as through the pointers 18 are the threaded shanks 20 of headed screws 21 the said shanks being re ceived in nuts 22, which are disposed back of the body plate 1 and are provided With rectangular portions 22*, Fig. 3, that are dis-' posed and slidable in the slots 1 of the Wings 2 and in the slots 16' of the plates15.

. The manner of using my novel device tov measure the angle of a conical shaft is clearly shown in Figure 1, and by reference to the said figure and in the light of the foregoing description, it will be manifest that when the two pointers are on the same degree of the scales 3. the angle will be accurately indicated.

At 24- in Fig. 7 is a lever pointer that is adapted to be pivotally mounted on the shank of the screw 6 and alongside a washer 25, Fig. 5, and to be used in conjunction with the scale 7. Figure 7 for the purpose of measuring the angle of a bore in a member 26,- towhich the body plate 1 is opposed squarely asclearlyshown in-,Fig. 7.

As-Will be observed-by reference to Figure 8, the head 9 of the endwise movable bolt 8 is provided with a V-shaped face, desirable for centering the device about a shaft.

In Figures 9 to 11 I have illustrated a modification of my invention which is a material simplification.

In the modified construction, 'a body plate 1 is provided with a graduated scale 7 on its face and adjacent to its outer end, and

said body plate is also provided with a wing 2 on which is a graduated scale 8. In the plate 1 is. a longitudinal slot 4: to receive threaded shanks 5 carried by a body having arms 6 and 7; the shanks 5* being equipped with nuts 9 as illustrated. Adjustably fixed by a set screw 10" in arm 6 is a centering pin 11 and'carried by the arm P is a ring 12 in which bear a plurality of equi-distant screws 13 through the niedium ofwhich the ring may be set upon an axle or the like after the manner shown best in Figure 11. At 17' is a jaw having a pointer l8 designed to cooperatewith the scale 8 In the pointer is an aperture, and extending through said aperture and a slot in the body plate 1 is the threaded shank of'a screw 21, the said shank being designed to be received in a nut disposed back of the body plate and being, by preference, of the same construction as the shank Q0, hereinbefore described, with reference to Figures Ito T.

The shaft is exactly centered in the link I 12 by centering the pin 11 and adjusting the screws 13".

the-rein, slotted plates bearing graduated scales and located fiatwise on the wings,

jaws disposed at right angles to the body plate and having portions connected to the body plate and also having pointers disposed parallel to the body plate adapted to coopera te with said graduated scales, and means for adjustablyfixing the scale-bearing plates and the jaws with respect to the body plate.

2. A measuring device, comprising a body plate having slotted wings, slotted scalebearing plates-located flatwise on the wings, jaws having portions at angles to the body plateand portions connected to said plate and also having pointers parallel to the body plate and the scale-bearing plates, and means for permitting endwise movement of the scale-bearing plates, while preventing bolt extending through said body plate and removable therefrom, and having a head in which is a centering face, and means whereby said bolt may be moved endwise through swinging movement thereof, and adjustably fixing the scale bearing'plates' and the jaws. 1 with respect-to the body plate. I 3. A measuring device comprising a, body plate, and an endwise'movable transverse the body plate without turning of the bolt I about its axis. 1 I j -12. A measuring device comprising a. body plate having a sleeve at its back and also having wings and slots therein extending lengthwise of the wings, slotted plates hearing graduated scales and located flatwise on the wings, jaws disposed at right angles to the face of the body plate and having portions connected thereto and also having portions at angles to the body plate and pointers parallel to the body plate and adapted to co I operate with said graduated scales, means to adjustably fix the scale bearing plates and the jaws with respect to the body plate. an endwise movable transverse bolt extending through the said sleeve of the body plate and I having ahead in which is a centering face and also having a longitudinal groove, and a screw bearing in the sleeve and extending into the groove in the bolt.

In testimony whereof I affix my signature.
